Valve performance and reliability is key to compressor performance. By paying careful attention to reliability in every aspect of the design, we’ve created a valve that in many applications can run more than 50 percent longer than other valves before needing service. We’ve proven it in thousands of hours of tests, many at high speeds and high temperatures, with a wide range of gases. Our engineers select the most appropriate valve based on their extensive experience as well as tools such as our Dynamic Valve Analysis (DVA) program.

Most compressors produce more capacity than needed to allow for process control. The excess capacity is typically recycled to the inlet of the compressor to meet demand. The energy required to recycle the excess capacity is wasted.

Variable capacity control systems give operators the ability to adjust compressor capacity to demand, eliminating recycle. This reduces energy usage and operating costs.Variable capacity control devices are becoming more prevalent in the process market because of increased energy costs and the desire to save energy and related expenses whenever possible.
